Sultry: Nicola has been unveiled as the new colour ambassador for Dulux

The five-piece started rehearsals this week, which sees them in their first concerts together since they last toured in 2009.

However,
it appears the show hasn't been such a sell-out as they hoped with some
ticketholders trying to shift their seats for less than face value on
viagogo.

Indigo was predicted as this year's colour by a team of global colour and trend experts who study interiors, fashion, beauty, design and even social and economic influences throughout the world.

Colour in demand: Nicola nearly blends into the indigo wall

Louise Smith, Dulux Senior Global Colour Designer, said: 'We’re currently living in turbulent times and this is having an effect on the colours we want to wrap ourselves and our homes in. Blue is a key fashion colour for 2013 and is set to be a wardrobe and interior favourite throughout the year.

'Indigo adds a surprising, elegant strength and shows you are quietly confident with colour, which is why we felt Nicola would be the perfect ambassador for Indigo Night; an advocate of being bold with her natural colour and champion of colour in her everyday life.'

To celebrate the announcement of Indigo Night as the Colour of the Year, Dulux is offering a limited supply of free testers, which can be ordered online through www.dulux.co.uk/colouroftheyear.
